Unlocking our iPhones has come a long way since the touchpad days. While Face ID offers a seamless experience, it’s not without challenges, especially for the stylish lot sporting sunglasses. Let’s delve into how you can make Face ID recognize you even behind those trendy sunglasses.

Can You Get Face ID To Work With Sunglasses?

Absolutely! While certain sunglasses might give Face ID a moment’s pause, there are tweaks and adjustments to make sure you can enjoy the sun and swiftly unlock your iPhone.

Understanding the Face ID Mechanism

  • How Face ID Uses Camera and IR Technology: Face ID combines camera and infrared (IR) technology to capture a detailed scan of your face. This scan is then matched with the data stored securely in your iPhone’s enclave.
  • The Attention Feature: One of Face ID’s standout security features ensures that the phone unlocks only when you are actively and directly gazing at it. This means passive attempts, like someone holding your phone to your face without your knowledge, would be unsuccessful.

How Does Face ID See Through Sunglasses?

Face ID doesn’t exactly “see through” sunglasses. Instead, it tries to recognize the rest of the facial features and matches them with its stored data. The infrared (IR) technology can, in many cases, penetrate sunglasses to detect eyes, but this isn’t always the case with all sunglasses.

Common Issues with Face ID & Sunglasses

  • Initial Rejections: If it’s your first time rocking those shades, Face ID might take a moment to adjust. This usually results in a prompt for a passcode.
  • Polarization Woes: Sunglasses with polarized lenses can pose issues. Their design sometimes impedes the iPhone’s sensors from recognizing eye movement, leading to Face ID hiccups.

Why Does Face ID Work With Some Sunglasses and Not Others?

The variance lies in the glasses themselves. Polarized sunglasses or those with certain coatings may block or interfere with the IR beams used by Face ID.

Without further ado, here’s what you can do:

Additional Tips:

  • Help Face ID Evolve: Whenever Face ID fails to recognize you, promptly input your passcode. This action helps the system adjust and recognize the new look next time.
  • Quick Security Boost: If ever in doubt, a quick press of the side and volume buttons simultaneously will disable Face ID, defaulting to the passcode requirement for extra safety.

As technology advances, so do the nuances we need to understand for smooth operation. While Face ID might sometimes be confused by sunglasses, with a bit of patience and tweaking, it can continue to serve as an effective and convenient security measure.
